Hair/Crazy in Love from/by Hair/Beyoncé feat. Jay-Z is a mash-up featured in Hairography, the eleventh episode of Season One. It is sung by the New Directions, with solos from Artie and Mercedes.

They sing it in the choir room for the Haverbrook School for the Deaf. The performance contains a lot of "hairography," or frequent hair tossing (with all of the boys wearing long wigs). This performance was inspired by the Jane Addams Academy girls' performance of Bootylicious (they introduced the hairography). After the performance, the Haverbrook Glee Club looked freaked out and Will didn't look impressed with what he had done.
